Who controls it
cbBTC is a Bitcoin wrapper that Coinbase issues. Coinbase holds the underlying BTC and can freeze the token.
- Holder’s claim
- The holder owns a token that Coinbase is obliged to redeem 1:1 for BTC. The holder does not own bitcoin.
- Redemption or sale
- Eligible Coinbase customers mint or redeem cbBTC for BTC directly through Coinbase. Holders on other venues sell in the market.
Dependencies
- Coinbase custody and jurisdiction
- Coinbase's mint, burn, and freeze authority
- The token contract and any bridge across chains
- Market liquidity for the peg
Advisor notes
cbBTC does not give a client Bitcoin’s resistance to censorship. In place of Bitcoin’s own settlement, the client relies on Coinbase as custodian and on the regulators Coinbase answers to.
A named organization or administrator controls issuance, transfers, reserves, redemption, or address restrictions. This grade can sit beside a sound reserve, a useful product, or a fitting role in a client account. It records who can act on the token and passes no judgment on the product.
